Portland Timbers interim head coach Gavin Wilkinson has warned his players new coach Caleb Porter is watching.

Porter will take over as the team's head coach this winter.

"For us, it's a matter of staying focused and keeping the guys concentrated and making sure that they know that maybe playoffs aren't an option, but for self preservation and personal pride and their personal integrity, it's, not up for grabs, but maybe at stake," Wilkinson said Friday. "I think it's important to show what they can do individually and collectively.

"And the only way they're going to get to play in the Seattle game is if they play well against D.C."
